1，关于鸿蒙系统

---

OpenHarmony是开放原子开源基金会（OpenAtom Foundation）旗下开源项目，定位是一款面向全场景的开源分布式操作系统。
OpenHarmony在传统的单设备系统能力的基础上，创造性地提出了基于同一套系统能力、适配多种终端形态的理念，支持多种终端设备上运行，第一个版本支持128K-128M设备上运行，欢迎参加开源社区一起持续演进。
针对设备开发者，OpenHarmony采用了组件化的设计方案，可以根据设备的资源能力和业务特征进行灵活裁剪，满足不同形态的终端设备对于操作系统的要求。可运行在百K级别的资源受限设备和穿戴类设备，也可运行在百M级别的智能家用摄像头/行车记录仪等相对资源丰富的设备。

2，根据文档编写Dockerfile

---

环境搭建是第一步。
我觉得应该给个官方的Dockerfile，这样直接下载镜像得了。

https://gitee.com/studyharmony/linux-build/blob/master/Dockerfile

# 构建命令：
# docker build -t openharmony:dev . 

#使用 ubuntu:18.04 做基础镜像减少大小。
# 然后安装构建鸿蒙系统需要的软件
 
FROM docker.io/ubuntu:18.04

# https://developer.aliyun.com/mirror/
# https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.3e221b115c0SRA

# 使用阿里云镜像地址。修改debian apt 更新地址，pip 地址，设置时区。

index-url=http://mirrors.aliyun.com/pypi/simple" > /etc/pip.conf && \

# 按照官方的方法继续软件安装：

# 将Linux shell改为bash 
RUN apt update &&  apt-get install -y curl && rm -rf /bin/sh && ln -s /bin/bash /bin/sh

# 这个是很少变的，放到前面
# 安装gn && 安装ninja && 安装LLVM编译工具链 && 安装hc-gen

RUN cd /opt && curl -O https://repo.huaweicloud.com/harmonyos/compiler/gn/1523/linux/gn.1523.tar && \
    tar -xf gn.1523.tar -C /opt/ && rm -f gn.1523.tar

RUN cd /opt && curl -O https://repo.huaweicloud.com/harmonyos/compiler/ninja/1.9.0/linux/ninja.1.9.0.tar && \
    tar -xf ninja.1.9.0.tar -C /opt/ && rm -f ninja.1.9.0.tar

    pip3 install setuptools kconfiglib pycryptodome six ecdsa && \
    rm -f /usr/bin/python && ln -s /usr/bin/python3.8 /usr/bin/python


# 使用： 
# mkdir -p data && docker run -it -v $PWD/data:/data openharmony:dev bash

然后构建一个docker镜像：

docker build -t openharmony:dev .

3，使用镜像构建第一个程序Hi3516

---

没有设备，就研究烧录了。

参考
https://openharmony.gitee.com/openharmony/docs/blob/master/quick-start/%E5%BC%80%E5%8F%91Hi3516%E7%AC%AC%E4%B8%80%E4%B8%AA%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F%E7%A4%BA%E4%BE%8B.md

镜像可以多次使用，映射一个本地data 文件夹：

mkdir -p data && docker run -it -v $PWD/data:/data openharmony:dev bash

进镜像之后

cd /data
mkdir code-hi3516
cd code-hi3516
curl -O https://repo.huaweicloud.com/harmonyos/os/1.0/code-1.0.tar.gz
tar -zxvf code-1.0.tar.gz

# 直接执行 即可：
python build.py ipcamera_hi3516dv300 -b debug

最后显示构建成功，省略中间好多步。

4，构建另外一个程序Hi3861

---

和第一个类似，但是下载了代码之后执行编译：

  python build.py wifiiot

报错如下，看来和Hi3516 的项目构建的东西还是不一样的。

5，总结

---

使用Docker镜像的方式，能最少的建设不同设备搭建环境的差异。
但是只成功构建了 Hi3516，没有构建成功 Hi3861 的Demo。
而且，我也没有设备。能成功构建，Demo 肯定可以烧录进去。
下面的就不研究了。接着开始看看相关的代码啦。
